Black holes destroying Earth is possible in our lifetime

[K.I.L.E.R]

I'd like to believe that we won't get killed by a black hole but unfortunately no one can dismiss every single possibility.

Upon looking for solutions to the problem I wound up at a few sites showing that it's completely possible for a scientist to accidentally create a black hole and kill us all.

Sucked into a microscopic black hole

You will need: a microscopic black hole.
Note that black holes are not eternal, they evaporate due to Hawking radiation. For your average black hole this takes an unimaginable amount of time, but for really small ones it could happen almost instantaneously, as evaporation time is dependent on mass. Therefore your microscopic black hole must have greater than a certain threshold mass, roughly equal to the mass of Mount Everest.
Creating a microscopic black hole is tricky, since one needs a reasonable amount of neutronium, but may possibly be achievable by jamming large numbers of atomic nuclei together until they stick. This is left as an exercise to the reader.
Method: simply place your black hole on the surface of the Earth and wait. Black holes are of such high density that they pass through ordinary matter like a stone through the air. The black hole will plummet through the ground, eating its way to the centre of the Earth and all the way through to the other side: then, it'll oscillate back, over and over like a matter-absorbing pendulum. Eventually it will come to rest at the core, having absorbed enough matter to slow it down. Then you just need to wait, while it sits and consumes matter until the whole Earth is gone.
Earth's final resting place: a singularity with a radius of about nine millimetres, which will then proceed to happily orbit the Sun as normal.
Feasibility rating: 3/10. Highly, highly unlikely. But not impossible.

I've previously read about scientists creating artificial black holes in labs.
What would happen if one of those black holes escaped?
Can magnets really hold them permamently?
What happens if the magnets run out of energy and scientists forget to change them, worse what happens if they weaken enough for the black hole to escape and grow larger by eating more and more matter?

Eventually our planet would be consumed by a black hole simply because some idiot forgot to change a magnet.
Isn't this horrendously dangerous?
I can't believe people are worried about global warming when we probably won't survive the next decade.

As likely as Bin Laden visiting Bush for Xmass...

There's more chance of me going bok and killing you KILER, than any black hole....actually, the odds are pretty good...

If someone manages to make a micro-black-hole in one of those gigantic particle accelerators that exist here and there, it will have a rather short lifetime. The largest collision energy that the 27-kilometer LHC will be capable of is around 1150 TeV, corresponding to a mass of 1.9e-21 kg. If that mass takes the form of a black hole, it will have a lifetime of about 10^-87 seconds if Stephen Hawking is right about black-hole radiation.

In any case, Earth is hit by cosmic rays every now and them that have thousands of times more energy than what even the mighty LHC will ever be capable of; given that these are not already making the Earth implode into a black hole, I don't think there is anything to fear.

Also, death by Earth imploding into a black hole would presumably be extremely quick and as such painless; the situation is rather different from what would happen if the Earth e.g. entered the accretion disc of a large pre-existing black hole.

i bet it would make you really dizzy.

Not really new - 'Earth' from David Brin describes exactly that scenario and its possible consequences.

Interesting plot, too bad the book itself was boring as hell - i did finish it (somehow), but I can't even remember the ending....

Worst case scenario, how would I die?

 

[ZoinKs!]

Slowly and painfully.

In the case of Earth imploding into a black-hole? The Earth would be sucked away from beneath you, you will be free-falling for some time (a few minutes), then, when you reach the actual black hole beneath you, you will be crushed into a mathematical point over a timespan of a few milliseconds. Before you reach the black hole, though, you will feel effects like tidal forces and spaghettification, which will be quite painful during the last 2 seconds before you reach the black hole itself.

Would I at least get a chance to shoot myself?

 

[Neeyik]

Don't worry - we'd all do it for you.

 

[NANOTEC]

Give me a few seconds while I load my shotgun.

Why does everyone want me dead?

Why does everyone want me dead?

So that you may raise yourself three days hence and confim their beleif in your divinity...
